Metabolite Identification
Common NameHymenoxin
DescriptionHymenoxin belongs to the class of organic compounds known as 8-o-methylated flavonoids. These are flavonoids with methoxy groups attached to the C8 atom of the flavonoid backbone. Thus, hymenoxin is considered to be a flavonoid. Hymenoxin has been detected, but not quantified in, a few different foods, such as herbs and spices, peppermints (Mentha X piperita), and sunflowers (Helianthus annuus). This could make hymenoxin a potential biomarker for the consumption of these foods. Based on a literature review very few articles have been published on Hymenoxin.
